ActiveRecord :: Enum - PG :: InvalidTextRepresentation：ERROR：整数的无效输入语法：

问题描述

我有一个奇怪的错误，希望有人能指出我正确的方向。我有一个名为Organizations的模型，以及一个名为 department 的属性，请参见下面的架构摘录：

  t.integerdepartment，默认值：0 
  

已定义了此属性的枚举，因为我使用的是 ，如下所示：

 枚举部门：[：会议，设计团队，服务，俱乐部，事件，通信] 
  

但是当我查询 JobPosting.joins（job：：organization）其中（组织：{department：'meetings'}）我得到一个错误，内容如下：

PG :: InvalidTextRepresentation：错误：整数的无效输入语法：会议

FYI：组织has_many作业和作业has_many JobPostings。 >

但是当我查询 Organization.where（出发点

任何帮助将不胜感激。

解决方案

这适用于ror5。

  JobPosting.joins（job：：organization ）.where（organization：
 {department：Organization.departments ['meetings']}）
  

我甚至不确定如果枚举是在ror3。

I am having a strange error and was hoping someone could point me in the right direction. I have a model called Organizations, and a attribute called department, see the excerpt from the schema below:

t.integer  "department",  default: 0

Inside my model have defined my enums for this attribute, as I am using ActiveRecord::Enum, like below:

enum department: [:conferences, :design_teams, :services, :clubs, :events, :communications]

But when I query, JobPosting.joins(job: :organization).where(organizations: { department: 'conferences' }) I get an error that reads:

PG::InvalidTextRepresentation: ERROR: invalid input syntax for integer: "conferences"

FYI: An Organization has_many Jobs, and Job has_many JobPostings.

But when I query Organization.where(department: 'conferences') it works.

Any help would be greatly appreciated.

解决方案

This works on ror5.

JobPosting.joins(job: :organization).where(organizations: 
{ department: Organization.departments['conferences'] }) 

I'm not even sure if enum was available in ror3.
